Improvement in plows

IMPRovEMEn-r IN PLows.

Specification forming part of Letters Patent No. ll 1,965, dated February 21, 1871.

To all whom 'it 'may concern:

Be it known that I, JAMES OLIVER, of South Bend, in the county ot' St. Joseph and State ot' Indiana, have invented certain Improvements in Flows, of which the following is a specitication z ".ihc nature ot' my invention consists, first, in the peculiar forni ot' the colter, which is cwt with the plow-point; second, a slotted c, which is placed between the handles at the heel ot' the beam, which is secured to the brace by nienns of a bolt.

Figure is a perspective view. Fig. 2 a plan, 3 a front elevation, Fig. 4 a rear View, ot my improved colter, and Fig. 5 a

-rear view ofthe ohl-stylc colter when formed with the plow-point.

a is the pion-point, the rear end of which extends upward toward the beam, thereby Aiorming n colter, l). hns the saine curve that the mold-board has, thereby torn-ing almost a continuous curve from the front edge ot the coltcr to the heel ci" the mold-board.

ln the old style of colter that is cast with the plow-point the side is straight from its upper end to wliere'it meets the blade of the {now-point, thus forming an angle, as will be seen by reference to Fig. but by reference to Fig. etit will be seen that my colterhas a continuons curve from its upper end, which runs into the blade ofthe plow-point, which curve, being the same as that of the moldboard, makes the draft ot' the plow much lighter and produces better work.

.o the standard, which is curved from the lineof the point over and toward the mold-l board, as shown in Fig. 3, hns.I )lacing its upperend, on which the beam rests, some dis.

The side of this colter' tance inside the line of the point, and also bringing the beam nearerV equidistant from the handles. In the upper end of the standard c is a slot, as shown in Fig. 2, 'which admits of the adjustment of theA beam. beam d is secured to the standard c' by a bolt, g. Between and secured to the handles is a brace, e, in which 'are slots f. This brace passes under the heel of the beam," and they are secured together by means of a bolt, g', which passes through them. The end of the brace next to the mold-board is curved dow11` Ward, and secured to the handlenn that side at or near where the handle is secured to the mold-board, thereby giving it support. y

Sometimes, while the plow is being drawn forward it does not vrun eve11ly-thats, in clines to one side or the other; but by loosening the bolts g g the beam may be adjusted to either side, as desired, which will cause the` plow to sit squarely on its base and run true. The means ot' adjustment also enables the operator to make a wide or narrow furrow at Will, or the plow can easily be adapt-ed to two or three horses.

1. A colter and plow-point formed of one piece, when said colter has the same curve given it, or nearly so, that the mold-board of the plow has to which it is to be attached, substantially as shown and described. Y

2. In combination with the standard o, when curved, as described, the curved, grooved, and

slotted brace c and beam d, when all the parts are arranged as and for the purpose specified.
